PROTECTIVE CAP FOR WOOD PIL-ING.

Application filed November 18, 1927. Serial No. 234,224.

The present invention .is concerned with the provision of a protective cap designed to prevent rain water from collecting on the top of wooden pilings and rotting the pilings. Previous attempts to solve this problem by the use of tar-paper have been unsuccessful, due to the fact that water enters through the tack holes in the paper, and wherever the paper is creased it soon loses its waterproof quality.

In accordance with the present invention, I have designed a metal protective cap which will overcome the above noted disadvantages, and which may be conveniently and expeditiously applied to any pile head.

Other objects of the invention are to provide a protective cap of this character, which will be of simple, practical construction, rugged, durable and eiicient in use, and well suited to the requirements of economical manufacture.

With the above noted and other objects in view, the invention consists in certain novel features of construction and combinations and arrangements of parts, as will be more fully hereinafter set forth and pointed out in the claims. The invention may be more fully understood from the following description in connection with the accompanying drawings, wherein- Fig. 1 is a fragmentary view partly in vertical section showing one of my protective caps in applied position on a bearing pile.

Fig. 2 is a sectional plan view showing the cap, and taken on the line 2-2 of Fig. l.v

Fig. 3 is a fragmentary view partly in elevation and partly in section showing the top of a fender pile with a modified form of cap embodying the present invention applied thereto. v

In Fig. 1 I have used the reference numeral to designate a bearing pile, and the numeral 1l to designate a cross timber supported thereby and retained against displacement by a drift-bolt 12 passed through the timber 11 and into the pile 10. The cap of the present invention, which in this instance is interposed between the top of the piling 10 and the supported timber 11, consists of a metallic plate 13 of slightly less diameter than the pile 10, having a downwardly turned peripheral flange 14 which is sharp edged, so that it may be driven into the wooden piling until the plate 13 lies flatly against the top of the piling. A central opening 17 in the plate 13 accommodates the drift-bolt 12 and is encircled by an upstanding sharp fiange 15 which penetra-tes the timber 11. Preferably, the opening 17 between the timber ll and piling l2 is filled with asphalt or equivalent material as indicated at 16. By virtue of this arrangement, rain water cannot collect on the top of the piling 10, and moisture cannot seep through from the timber 11 and rot the piling 10.

In Fig. 3 I have shown a fender pile 10 capped with a device embodying the present invention. In this instance, the cap is in the nature of an unapertured circular plate 13il with sharp depending marginal flanges 14a, which may be driven into the pile. The cap if desired, may be additionally secured by the use of nails or equivalent securing devices 20 driven through the sides of the piling and penetrating the flange 14a. In this instance also, there 1s no opportunity for Water to collect on the top of the piling and rot the same.

Obviously, various changes and alterations might be made in the general form and arrangement of the parts described without departing from the invention. Hence I do not wish to limit myself to the details set forth, but shall consider myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of the appended claims.

I claim:

1. As a new article of manufacture, a protective cap for wooden pile heads including a flat metal plate and a sharp marginal flange turned downwardly from the plate and ada-pted to be driven into the pile. f

2. As a new article of manufacture, a protective cap for wooden pile heads including a at metal plate and a sharp marginal flange turned downwardly from the plate and adapted to be driven into the pile, said plate having an opening therein adapted to accommodate a drift bolt for securing a superimposed structure.

3. As a new article of manufacture, a protective cap for wooden pile heads including a flat metal plate and a sharp marginal flange turned downwardly from the plate and adapted to be driven into the pile, vsaid plate having an opening therein adapted to accommodate a drift bolt for securing a superimposed structure, and an upstanding sharp flange around the opening adapted to penetrate the superimposed structure.

4. A wooden bearing pile and a wooden Cross timber supported thereon7 a protective Cap on the head of the pile including a metal pla-te, a turned-down sharp edged marginal flange on the plate penetrating the pile, said plate having a central opening therein receiving a drift bolt connecting timber and pile, and an upturned sharp edged flange integral With the plate around the opening and entering the timber.

5. A Wooden bearingpile and a Wooden cross timber supported thereon, a protective cap on the head o'f the pile including a metal
